Who’s Got Liquids?

An article by Canadian consultant Mike Priaro in the 7th July, 2014 edition of Oil andGas Journal, “Grosmont carbonate formation increases Alberta’s bitumen reserves”, included the following tables:

Mr Priaro’s estimate of Canada’s recoverable bitumen is 818 billion barrels. Almost all of that is in Alberta. Combined with their coal resources, Alberta has the biggest fossil fuel resource on the planet. I have updated my estimate of what some of the major countries have in the way of fossil fuels in this table:

The highest value fuels are those that can be used as liquids in transport. High quality coal produces 2.2 barrels of liquids through a FT plant. In the following graphic I have used a factor of 2x to convert coal to its oil equivalent. Six thousand cubic feet of gas has the energy equivalent of one barrel of oil. Natural gas can be used directlyin some transport applications. Putting it through an FT plant to make diesel, for example, would lose at least 30% of its initial energy. Natural gas has traditionally traded at the oil price in the US and conceivably might return to close to that level in a tight market. So in the following graph, natural gas in TCF is divided by six to produce its oil equivalent in billions of barrels. This is the graph:

Bakken Oil Peak by Jean Laherrère

This is a guest post by Jean Laherrère

The problem of forecasting future Bakken production is that estimating reserves of shale oil is harder than for conventional oil and is very unreliable because many confuse reserves and resources, and shale oil reserves depend more from economy than from technology. Many estimate the amount of hydrocarbons generated by the source-rock and believe that a significant percentage could be recovered: the study of the main Petroleum Systems in the world estimate than only about 1% will recovered in conventional fields, no more could be expected in unconventional fields.
US Shale gas production started in 1821 in Fredonia for lighting when whale oil price was about 2000 $2014/b, but was replaced by conventional oil in 1859 because a largely lower price.

How to estimate future production?

Drilling activity is a good way to model production with a shift.
In my MIT Paris paper «The end of the peak oil myth» MIT club de France- Paris 28 April 2014, I was convinced that North Dakota oil production will peak within 2014 using a correlation between oil production and shifted number of rigs, guessing the value of the shift and the relationship between rigs and production.

This April 2014 graph is wrong when adding present data at July 2014 (still rising after a minor peak in November 2013) and I have changed the shift from 20 months to 30 months and the correlation oil/rig, but I feel uncertain about the reliability of such graph.
When active in exploration I was used to drill 9 dry holes out of 10 wildcats: I am used to be wrong and I am not afraid of that. To make discovery you have to take risks.
My new model forecasts ND oil production peak in 2015 at less than 1.2 Mb/d, but again this new model could be wrong as the old one.

My modeling was based on the Montana oil peaks, which fit well with the number of rigs shifted by 12 months since 2000.

Bakken Production Data for June + EIA Data

08/16/201408/17/2014 Ron Patterson 120 Comments

The Bakken and North Dakota production numbers are in for June. There was a big jump in oil production in June. The Bakken was up 53,162 barrels per day to 1,028,352 bpd. All North Dakota was up 52,148 bpd to 1,092,617 meaning the area outside the Bakken was down about 1,000 bpd.

From the Director’s Cut:

May Sweet Crude Price = $88.31/barrel
June Sweet Crude Price = $90.03/barrel
July Sweet Crude Price = $86.20/barrel
Today’s Sweet Crude Price = $79.50/barrel (all-time high was $136.29 7/3/2008)

The drilling rig count was up one from May to June, and up two more from June to July.
The number of well completions increased as weather impacts eased in June with
significant rainfall on 2 days near Minot and 1 day near Dickinson. However, there were
still 6 to 8 days with wind speeds in excess of 35 mph (too high for completion work).

At the end of June there were about 585 wells waiting on completion services, a decrease
of 25.

For the first time in a couple of years he did not give us the exact number of new well completions, only that they increased. Last month there were 227 well completions and production was up 37,000 bpd so we can assume there were aroun 235 to 240 new well completions in June.

Well completions should not be confused with “additional wells producing. That is and entirely different figure.

Additional wells producing is new wells completed, plus previously shut down wells brought back on, line minus wells shut down. Sometimes this number goes negative as it did in December of 2013. That month “Wells Producing” dropped by 52 even though there were 119 new wells completed. All data is barrels per day.

GEOGRAPHICAL ANALYSIS OF WELL QUALITY IN NORTH DAKOTA

by Enno Peters

SUMMARY

I was interested in doing a geographical analysis of the oil production in North Dakota. Detailed information made freely available by the NDIC allowed me to analyze how, geographically, wellperformance has been changing over time, in the area of North Dakota where most oil is produced.

RESULTS

In the following animated gif, you will see part of North Dakota. It contains the North West corner that borders Montana and Canada. The scale is in miles, with a rather arbitrary origin. Projected on this map is a contour map. The numbers of these contours are the cumulative 1 year returns for wells drilled within that area, and the unit is 1000 barrels of oil (no gas). For example, contours with the value 50 mark the area in which wells produced at least 50 k barrels of oil in their first year.

I could calculate the surface areas of several levels of first year well returns, in order to determine the trend of these areas. In the following chart you can see for each year the (estimated) surface volumes for 3 levels of first year well returns, 50k, 80k, and 110 k barrels of oil.

The sudden increase in 2013 of estimated productive surface area, in which wells could produce at least 50 k barrels of oil in their first year, may be explained by

1) the fact that I could only use data until June 2013 (as the 2014 May data is currently the latest one available), and therefore the number of data points are 1/3 of what I have for 2012. The method to determine the contours may not be suitable with this number of data points.

2) changing well practices

3) entering of new formations

So far I suspect that it is mostly 1), but that 2) and 3) could also be part of the answer, and therefore recommend to mostly ignore the 2013 results for now.

As a guide to interpret these results, I estimate (based on a discounted cash flow analysis) that a well that returns 50 k barrels of oil needs a minimum WTI price of about $120; about $82 WTI is needed for 80 k wells or better, and a well that returns 110 k barrels of oil in its first year is about even with $64 WTI. These are rough indications; I have seen a good analysis that estimates 10% higher required WTI prices for these levels of well performance. With current prices that would mean that 50 k wells are not profitable, while 80+ k wells clearly are.

I further estimate that the estimated total oil return (EUR) of a well is just over 4 times its first year return.

EIA Petroleum Supply Monthly

08/01/201408/03/2014 Ron Patterson 136 Comments

The EIA has released its Petroleum Supply Monthly with C+C production numbers through May 2014. Of all the EIA data releases this seems to be the most accurate. However in some cases it is only as good as a few EIA employees guesses. And the more state data they have to work with, the better their guess.

The data in this report goes back to 1920 for total US production and to 1981 for individual states and offshore production. However I have chosen to shorten the time frame for my charts in order to better show what has happened recently.

US production was down 36,000 bp/d in May to 8,357,000 barrels per day. US production took off in mid 2011 when Shale production took off and has risen some 3,300,000 since. Of course there was shale production prior to this but it was only keeping US production on a relatively flat plateau.

Everyone is interested in the Bakken so I have combined the two Bakken states. Of course there is production in these two states outside the Bakken but this is the best I could do. Note that when the Bakken has one bad month as they had in December, it takes several months to get back to their prior production level.
